RUSSELL G. DUDLEY, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO THE DUDLEYSHUTTER WORKER AND BURGLAR ALARM'OOMPANY, OF NEW YORK, N. Y.

WORKER.

SPECIFICATION forming part of Letters Patent No. 315,393, dated April 7,1885.

Application filed July 12, 1884. (No model.)

To (1% whom it may concern.-

Be it known that I, RUssELL G. DUDLEY, residing at Jersey City, in thecounty of Hudson and State of New Jersey, have invented certain new anduseful Improvements in Shutter-Workers; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse IO the same, reference being had to the accompanying drawings, andto letters or figures of reference marked thereon, which form a part ofthis specification.

Figure 1 of the drawings is a face view of I 5 my device. Fig. 2 is alsoa face view of the inner portion of the window-frame. Fig. 3 isavertical sectional View, and Figs. 4, 5, 6, and 7 are detail views. i

This invention has relation to shutter-work 2o ing mechanism; and itconsists in the con struction and novel arrangement of devices, ashereinafter set forth, and pointed out in the appended claims. 1

In the accompanying drawings, the letter A designates the side of thewindow-casing, and B a shutter connected thereto by hinges 0.

Through the casing is bored apassage, D, at right angles to the plane ofthe window, and in this passage is fitted a tubular bearin g,

0 E. The outer end of the passage D is enlarged a little, as shown at F,usually forming an interior annular shoulder, G, upon which is securedan annular wear-plate, H.

Through the wear-plate, passage, and bearing E extends the rotaryoperating-shaft K, the outer end of which is provided with a fork, I, inwhich is pivoted a turning piece or articulation, J, to which is alsopivoted the inner forked end of the short tumbler L, form- By means of asimilar double-pivot articulation, J, the outer forked end of thetumbler L, which extends obliquely, is connected to a fork-bolt, m. Thearticulation-pieces J and J are made with plain bearing-balls (1,preferably, said faces working against the parallel inner surfaces ofthe fork branches, so that the joints have great strength to withstandthe leverage strain.

1? represents a lug having a base, I), which is secured to the shutter;or the lug may be at its base, as indicated at e.

formed on the lower hinge. The lug, however, is in vertical line withthehinge-pivots, and is slotted, as shown at N, to form a hearing forthe squared shank s of the fork-bolt m, which is thus rendered capableof adjust- 5 5 ment to bring it in line with the hinge-pivots. Thesquared shank s of the fork-bolt is formed with a threaded extension, 0,on which is applied a securing-nut, '2, whereby the fork-bolt is firmlyattached to the lug P after adjust 6o ment.

The inner end of the operating-shaft K is formed with a seat, 0, for therocking crank Z, the bearing (1 of which is slightly rounded- The seat ais made large enough to allow play to the crank, which is connected tosaid seat by a pin. A ratchet-plate, R, having a central bearingaperture, 9, for the inner end of the shaft K, is secured tothe insideof the window-casing. The crank Z is radially'arranged with refer enceto the ratchet-plate, and may be held in any position by engagement withthe teeth thereof. A spring, h, is usually provided in connection withthe crank to hold the latter 7. in engagement with the ratchet, exceptwhen a disengagement is purposely effected in or der to move theshutter. i i Thesedevices are readily applied and will be found strongand effective. ing-rod runs squarely through the casing, it can befitted to one of the narrowest dimen1 sions without interfering with theweight boxes. I p p I am aware that it is not new to employ agimbal-joint in connection with a shutter I worker, and I do not,therefore, claim such 9 device, broadly.

I am aware of the patent granted to L. (J. Dion, October 3, 1882, inwhich a single glmo bal-joint is used to connect the shutter with theoperating-rod, the, said rod passing diagonally through a windowcasing,and theref fore do not claim such devices.

Having described this invention, what I 5 claim, and desire to secure byLetters Patent, 1s-

1. In a shutter-worker, the combination, with the operating-shaft K,running horizontally through the casing, of the shutter-lug P, rot

As the operat- 8o the fork-bolt m, and the double gimbal-joint, wherebysaid shaft is connected to said forkbolt, substantially as specified.

2. In a shutter-worker, the combination, with a shaft runninghorizontally through the casing, of a double gimbaljoint and devices forconnecting the same with a shutter, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
